This buck is by far the biggest I've ever seen on my home place and has been seen day and night coming in regularly the past few days...that being said tonight was the first time he has presented good pictures to judge age and size! I would like to know what do y'all think his age is and what he would possibly score?

Legal for sure. Trophy is in the eye of the shooter, and knowing what you have in your area. Odds are pretty good that if you do not take him, he probably wont be around next year. At least that's what I've found on my place near Tyler. They get to about that size, and then the next year, not one picture of him again.
